There are several factors to take into account when choosing an industrial Gas Burner. Of course, you'll have to decide what flame and capacity you'll require. Additional considerations include burner rating, temperature requirements, and more.
You can find more information on our web, so please take a look.
Take into account the Gas Burner rating first. Your system might not be able to attain the necessary temperature or capacity if a burner is rated too low. The maximum input rating of the burner you choose should be higher than the maximum firing rate of your equipment.
Turndown ratio, or the ratio of maximum capacity to minimum capacity, demonstrates a burner's adaptability. Look for a burner with a higher turndown ratio if you need one that can manage a range of varied load profiles. It will prevent cycling. Increased burner cycling might result in excessive purge loss and add to the wear and tear on components. Make sure your final decision will allow you to function at both your smallest and largest load because process turndown can vary dramatically.
Although it decreases efficiency, more air is necessary for proper mixing, clean burning, and minimal CO emissions. Gas Burners are often graded as a percentage (%O2) of surplus oxygen measured at the stack. For the majority of industrial applications, 3% O2 is a good aim because it is equivalent to 15% more air.
Even though many Industrial Gas Burner Manufacturers promise emissions of 3% O2 at high heat, many burners start using more extra air as the fire dims. Watch out for burners that advertise "efficient" turndown at ratios greater than 10:1, as this may be using a LOT of extra air. Consider cycling an 8:1 burner at 3% O2 a few times an hour to maintain a system's temperature during off-peak hours.
When choosing your Gas Burner, keep mounting, access, and adjustment simplicity in mind. The burner mounting should make it possible to remove the head and get to other crucial components. You won't need to move other equipment, remove the wiring, or entirely disassemble the burner thanks to this. Some burners need the installation of large, difficult-to-install refractory monoliths that require a lot of care.
Consider the benefits and drawbacks of each of the following fuels before choosing a new Gas Burner system:

• Gasoline. The most popular gas for boiler systems is natural gas. It is frequently the most affordable gasoline and is easily accessible to individuals who are close to a line.
• Petroleum. Since many owners don't have access to natural gas or plan to utilise fuel oil as a backup, they frequently pick fuel. However, it can be expensive to get oil to the facility, and you'll pay more per BTU.
• Propane liquid. Despite costing more than natural gas, liquid propane is a common and affordable substitute. This gas type is regarded as a cleaner approach because it emits fewer emissions. Propane needs to be used with a vaporizer for large systems, which will increase the cost and complexity.
• No gas (Electric). The cost of electric heating is frequently higher than the cost of gas heating. However, they are tidy, quiet, and simple to operate.
Our experts advise choosing a burner with a control system that features an oxygen (O2) trim function. Oxygen trim modifies airflow by using a monitoring device that typically monitors oxygen and CO. In essence, the system constantly monitors and maintains an ideal air to fuel ratio. Sometimes a burner can have a Suntec Energy System added to it afterwards. However, installing O2 trim while installing the burner is more economical. O2 trim frequently offers a layer of combustion safety to your system and pays for itself very quickly.
It is advisable to put a variable frequency drive in the forced draught fan when installing a new burner (VFD). Any Gas Burner System that won't operate at full capacity all the time benefits greatly from a VFD. A VFD:
